Across 7 comparable scheduled runs in the observation period September 21–27, 2026, no single name pulls away from the pack on the AI Overview opening-control rail for this market.

Pattern on the observed surface

Luxury Real Estate Advisory · London · AI Overview · September 21–27, 2026

The panel is distributed rather than concentrated

The panel is distributed rather than concentrated. The top 2 actors together hold less than the remaining 8 combined, and the top 3 actors together hold less than the remaining 7 combined. The 9 sources behind Black Brick range from 11.85% down to 3.79%, a gradual slope rather than a sharp drop-off. Eight of the governed top-10 panel opened AI answers in all 7 comparable runs; the remaining two — eccord.com and hoa.org.uk — opened AI answers in fewer runs. The surface mixes focused sources and niche domains with one general-purpose platform, youtube.com, which holds a mid-panel position.

Why this reading matters

Luxury Real Estate Advisory · London · AI Overview · September 21–27, 2026

Black Brick holds the rank-1 position on this AI opening-control rail, yet its lead over Rightmove is just 1.18 percentage points — the slimmest gap at the top of the panel. Meanwhile the bottom half of the panel is populated entirely by focused sources and niche domains, with no second platform visible. The surface AI reaches for first on Luxury Real Estate Advisory London queries is shaped by specialist domains, not by aggregator or platform concentration.

Market implication

Luxury Real Estate Advisory · London · AI Overview · September 21–27, 2026

The distributed shape of this AI opening-control panel signals that no single source has locked down the opening slot on this observed surface across the 7-run window. For any actor monitoring AI visibility on the Luxury Real Estate Advisory London market, the observation reframes the opening-control rail as a contested space where cumulative volume is spread across the governed top-10 panel rather than concentrated at the top.

FAQ

What does AI opening share measure?
AI opening share captures which source AI Overviews reach for first when constructing an answer. It measures the opening slot — the source cited at the start of the AI-generated response — not general citation frequency and not organic search ranking.
Does this card prove a longer-term trend in AI opening behavior?
This observation does not establish a longer-term trend. It aggregates 7 comparable scheduled runs in the observation period September 21–27, 2026. AI Overview opening behavior is volatile across queries, models, and dates; future windows may produce different results.
How were the period values calculated?
Each actor's AI opening share is the sum of its opening counts across all 7 comparable runs divided by a single period-wide denominator. The panel is ranked by cumulative opening volume over the period, not by an average of daily values. AI Overview opening-control evidence was available on 7 of 7 runs in the window.
